Please note, there are Three Glass path correctors of different focal length's available to supply perfect color correction and to suit all focussing needs.
-Glasspath corrector, Factor 1.25 (#2456314) – moves focus out to a minimum 15mm (may vary slightly from scope to scope)
-Glasspath corrector, Factor 1.70 (#2456316) – moves focus out to a minimum 35mm (may vary slightly from scope to scope)
-Glasspath corrector, Factor 2.60 (#2456317) – moves focus out to a minimum 85mm specially designed for Newtonian telescopes.
Some people choose to have more than one compensator to allow for a different range of magnifications, firstly you should work out how much back focus your scope allows (with various adapters and diagonals in place), then choose a suitable compensator to push the focus out to encompass that distance (+/- 5mm would be advisable just to be confident as there is some small tolerances)
